Thanks to the network, we now have spoilers for both shows, as well as a dual preview with scenes from the upcoming seasons.

For LUCIFER, the big news is that Luci and Amenadiel’s mother has escaped Hell and the brothers will be teaming up to find her and make sure she doesn’t cause any trouble on earth. We’re also going to be introduced to a new LAPD officer, Ella Lopez. It was also announced that Michael Imperioli will be making a guest appearance as another angelic brother.

At the end of Season One, Chloe watched Lucifer die, only to come back to life, causing more confusion over who he really is. Meanwhile, her estranged husband, Dan (Kevin Alejandro), who is also an LAPD detective, came clean about his involvement in a corrupt case – jeopardizing not only his job, but also their relationship.

In Season Two, Lucifer and his brother, Amenadiel (DB Woodside), who have been sparring over Lucifer’s resistance to returning to the underworld, will now be brought back together for one common goal – to find their mother, Charlotte (Tricia Helfer), who escaped Hell. After all, Lucifer doesn’t take after his dad, so the parent he does resemble is sure to be quite terrifying. Lucifer’s work with the LAPD also is upended when the police force hires Ella Lopez (Aimee Garcia), a smart, tough forensic scientist whose mutual belief in both faith and science proves a point of interest to Lucifer.

With mom on the loose, Dr. Linda Martin (Rachael Harris), who has become not only a therapist, but also a confidante to Lucifer, will surely have a lot of advice to dole out. And, by the time she’s done with them, she may need a therapist of her own.

Meanwhile, GOTHAM will be introducing more Super-Villains and revealing more about the Court of The Owels.

The origin story continues on Season Three of GOTHAM, and the stakes are higher than ever, as Super-Villains more ambitious and depraved are introduced, and a realignment of alliances shakes up the fight for power in Gotham City.

Season Three will peel back the curtain on the infamous criminal organization known as the Court of The Owls. With the Indian Hill escapees on the loose, Jim Gordon (Ben McKenzie) must take matters into his own hands as a bounty hunter in Gotham. He makes it his mission to find Hugo Strange (guest star BD Wong), the mastermind behind the horrifying Indian Hill experiments, and Fish Mooney (guest star Jada Pinkett Smith), one of Strange’s subjects. Meanwhile, GCPD Detective Harvey Bullock (Donal Logue) and Captain Nathaniel Barnes (Michael Chiklis) remain at the forefront of the fight against crime in the monster-ridden city. Also, Bruce Wayne (David Mazouz), with the help of his trusted butler and mentor, Alfred Pennyworth (Sean Pertwee), and former Wayne Enterprises employee, Lucius Fox (Chris Chalk), discovers there are still more secrets to uncover regarding his parents’ murders.

As the city sinks deeper into chaos, GOTHAM will continue to follow the evolving stories of the city’s most malevolent villains: The Penguin (Robin Lord Taylor); Edward Nygma/the future Riddler (Cory Michael Smith); Selina Kyle/the future Catwoman Camren Bicondova); Barbara Kean (Erin Richards), Tabitha Galavan/Tigree (Jessica Lucas) and Butch Gilzean (Drew Powell). The series also will catch up with the future Poison Ivy (Maggie Geha), who, after an encounter with a monster from Indian Hill, finds herself reborn as a young woman who’s harnessed the full power of her charms; and will dive into the origin stories of Jervis Tetch/Mad Hatter (Benedict Samuel), a talented hypnotist teetering on the edge of madness; and the Tweed Brothers.

GOTHAM and LUCIFER return for all new seasons on Monday, September 19 at 8:00 p.m. and 9:00 p.m. ET/PT.
